Reduced feedrate on 2nd reference Pass.

mendelevium

The option to reduce the homing feed-rate for 2nd reference Can be set by 1-normal feed rate or 2-To halve the feed rate. What happens if it is made 3 or 4? Will it ignore and home with normal feed?

Thank you.

It is just the divisor, so 3 will be 1/3 of the speed unless it gets below the minimum speed depending on acceleration and steps per mm.

It does not seem to have any effect....

these are my settings

I have mechaduinos on X & Y.

Z steps per mm = 800

Z Feed Homing 50

Z Max feed 12

Acc 1300

Z Print Speed 200

Do you suggest changing any of these? I think the 2nd homing process is important since

the switch would behave better at a slower speed and the Z position is mighty important considering

it effects the first layer.

Any tips wlecome with thanks.

Sure you are using Repetier-Firmware and not a other one. For repetier and Z axis the reduction factor is defined in

ENDSTOP_Z_RETEST_REDUCTION_FACTOR

What makes no sense in your valus is if z max feedrate is 12 why do you print with 200mm/s and home with 50mm/s? Home will be reduced to 12 as that is max value. and even with factor 4 reduced homing is 50/4 = 12.5 and still higher then maximum speed so also reduced to 12mm/s.

mendelevium

of course I am using repeter...

yes I have ...ENDSTOP_Z_RETEST_REDUCTION_FACTOR 2 (can be changed to say 4, 5 etc)

sorry I made a mistake..

Z steps per mm = 800

Acceleration

Print Z 200

Move Z1300

Feed

Z Max feed 12

Z Feed Homing 50

sorry for my mistake.

Many thanks in advance.

Ok, but as already said if you limit speed to 12mm/s homing should not be higher - it gets reduced to 12mm/s anyway and that is why reduction is still the recduced to 12mm/s speed.
